CVE-2026-49972

Estado: AplazadaAlta (7.7)—

Laravel-Mediable before 7.0.0 contains a file upload vulnerability that allows unauthenticated attackers to achieve remote code execution by uploading a file with an embedded PHP extension disguised within a double extension such as shell.php.jpg. The PATHINFO_FILENAME extraction preserves the inner .php extension in the base name, and on misconfigured Apache or nginx servers that execute any filename containing .php as PHP, the stored file is interpreted as executable code while all MIME type, extension, and aggregate type validation checks pass due to the outer .jpg extension.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

CWE-434 (validación de carga de archivos) + AV:N/PR:L permite a atacante autenticado cargar PHP disfrazado (.php.jpg) en servidor mal configurado, logrando web shell y ejecución de código remoto. La pista refuerza T1210+T1505.003.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
